Has anyone had issues of drivers heated seat not working, the cooling ventilation works on occasions but heating has just given up the ghost, all other heating and ventilation working on all other seats?

Got same problem, think there's been a few threads on this but haven't seen anything about a fix. My cooling works but heating cuts off after a few secs.

If the same as a 322 (which i think they might be?) they have peltier units top & bottom and the heater element fails leaving them just blowing out cold air!

Yes but how do we find out which ones ? Bothe my sheets cool but won't heat and my iiD won't ldenify any fault .
I suspect it's the backs as the ducts break and cause problems . 2008 MY Supercharged
